Works great!By Seanon 11/20/2012

Works great - added to my Max cap unit - along with a flush kit and appropriate flow restrictor - and wonderful things happened.

Note prior to this I had the CDP8800 booster pump dialed in at about 70-75 PSI (depending on filter lifecycle) with a single membrane since my utility water was normally 40-50 PSI which is borderline.

This installed quick and easy. Only thing I wish is that BRS had the option to order it with a pressure gauge (or at least with a plugged pressure gauge hole) to match my first membrane.

I primed everything, and also replaced my original membrane at the same time (bought her at BRS same order), ran a flush for good measure, then turned the system into production - measured waste water to product water ratio - it went from 5:1 to 2:1, and TDS rejection shot way up - post filter, I am at about 170PPM. Single membrane was throwing off 5-8 PPM product after running for awhile and settling down. Now, I am seeing 1PPM! That may not seem like much, but saves a lot of DI life, and makes for a 99.41% rejection rate! It's kept this up for 4 months now - I think flushing for a good minute at start and shutdown makes some difference too.

Added this unit to the 6 stage RO/DI unit I bought from BRS and it has been installed for 60+ days now. It works great. With the added booster pump that has been giving me 85psi, the 150 kit has been more than cutting my waist water in half. For each gallon of good water I only produce 1.5 gal of bad. Love it and I would buy it again.

Added this to my 90GPD 5 stages RODI system. Loved it. Still produces 0 TDS water but much much faster and less less waste.
Great buys.

Well worth the price to double your water capacity as well as reduce the waste water. Very easy to hook up.

I have the 75 GPD RODI system, was putting out too much waste water. I added the 150 GPD water saver kit and it has cut down on the waste water. It runs about 1:1 ratio. I can fill a 5 gallon jug in about 55 minutes.

I added the water saver upgraded after already owning and running a 6 stage chloramine ro/di unit. My water is not the ratio of waste to ro/di water was ridiculous. I added this and now im able to make water a lot faster and my waste water is a lot less. This add-on was easy to install and has increase production without hindering water quality.

Just got the upgrade kit and installed it following the easy instructions from the video. This is a must have upgrade that will save you time and money.

This a great addition your a RO/DI system to help produce more water and also produce less waster water which is always nice. It is recommend to have at least 65Ppsi for it to operate optimally.

This kit doubles your RO/DI output, while cutting your waste in half. So you make twice the water in the same time you did previously AND dump less down the drain... all for a reasonable price. What's not to like? Being nice to the earth (and your water bill) and cutting the time it takes to make purified water... sounds like a win win situation to me.

Oh and there's a handy video on the product page showing how to hook it up. Beautiful.

If you are getting a new RO/DI unit, get it pre-installed. If you already have one, buy this to up your output and halve your waste - it's good earth saving karma.

Needed more water...By moore1811on 5/24/2012

and I got it! I'm not patient enough for the 75gpd, so I opted for the 150gpd upgrade for that reason and also to reduce the amount of waste water. My production has doubled and my waste water halved. Install was easy with the provided video above. Highly recommended!
